Abstract
Case 1: An 8-year-old girl with a prodrome of fever and headache presented with generalized
tonic clonic seizures. She had florid meningeal signs. Laboratory investigations revealed
elevated liver enzymes. Cerebrospinal fluid had pleocytosis and elevated protein.
Immunoglobulin M antibody against hepatitis A virus (HAV) was positive in serum. She
recovered without sequelae.
Case 2: A 10-year-old girl with HAV infection developed progressive pancytopenia,
coagulopathy, and worsening liver function. She fulfilled the 2009 diagnostic criteria
of hemophagocytic lymphohistiocytosis (HLH). She had spontaneous resolution of HLH
without immunosuppressive therapy.
Central nervous system involvements of HAV usually resolve without sequelae. HLH following
hepatitis A is being increasingly reported and may resolve spontaneously.
